I scored mine from Amazon for $42 to the door, but it has since gone up to $58 to the door which is still a good bargain. Many of the majors did not meet the old Ford specification, so interesting this one does (nice find). It is supposed to be full synthetic, but I am not sure what that means from the Singapore point of view (i.e. is it synthetic like the US or Germany?).

Slightly off-topic but this is the first time I have noticed a CJ-4 actually claiming to meet WSS-M2C171-F1 spec. Have I just not been paying attention?

WSS-M2C171-F1 or WSS-M2C171-E? -E was for CJ-4; I have not seen any CJ-4 that meets -F1.

F1. Thanks...I wish I could go back and delete.

No worries! There were not very many of the majors that met the -E specification so to see this oil meet it with a fairly decent VOA is encouraging. My guess is this oil will be around for a while and it is fairly cheap so another option until Ford gets it together. I saw that Amsoil Heavy Duty 5W-40 also meets the -F1 specification as does Amsoil Max Duty 5W-40 so there are more options coming available for -F1.
